Two days later.

Nine a.m.

School of Life Sciences, Yenching University.

Inside Lab 1.

Zhao Heng was wearing a white dust-proof sterile suit, and he was watching Professor Li Hongwei redifferentiate the spinal cord into neural stem cells through fate regulation.

At Dongfang Hospital, I heard that Zhao Heng had contacted Professor Li Hongwei from the School of Life Sciences of Yenching University for stem cell cultivation, and Gao Jun's eyes fell out.

Gao Jun also readily agreed to Zhao Heng's request to come to observe, and after Liu Ziang knew about this matter, he even proposed to let Zhao Heng rest assured that he would go to Sun Xinxin's bed.

With the support of these mentors and friends, Zhao Heng naturally came to observe Professor Li Hongwei's operation on the spot without any burden.

To be honest, although such an opportunity is rare, it is basically useless to others, because it is too high-end, you can't read it, and you can't learn it.

Just when Li Hongwei was operating attentively, Zhao Heng suddenly saw that from Li Hongwei's body, a white light cluster that Zhao Heng was very familiar with but had not been seen for a long time fell.

Zhao Heng was very excited at the moment, he had made so many preparations, and finally waited.

Familiar with the road, Zhao Heng's heart moved, and the white light that only Zhao Heng could see turned into a streamer and drilled into Zhao Heng's mind.

The prompt sound of the system also sounded at this moment, and Zhao Heng never felt that this prompt sound was so pleasant.

With the integration of "Cell Fate Regulation (Mastery)", Zhao Heng suddenly has a very in-depth understanding of this technology, which can be said to be very high-end and difficult, comparable to the level of a genius biological scientist who has studied for decades.

However, Zhao Heng noticed that the skill of dropping and picking up fusion from Professor Li Hongwei was only at the proficient level, which showed that there was still a lot of room for improvement in such a technique.

Here, Li Hongwei had already finished an operation, and during a short break, he saw that Zhao Heng was so focused, so he asked him: "Xiao Zhao, do you know what two fate choices stem cells mainly experience in the process of development?" ”

Li Hongwei asked, in fact, it is equivalent to teaching.

Therefore, he didn't expect Zhao Heng to answer at all.

"It should be the process of self-renewal and proliferation, and the process of differentiation into functional progeny cells."

Zhao Heng retrieved the experience of the fusion that had just fallen from Li Hongwei in his mind, and said slowly.

“。

As soon as Zhao Heng replied, Li Hongwei was stunned for a moment.

"Professor, am I not right?"

Zhao Heng searched the experience in his mind again, and asked with some doubts.

"Well, yes, that's right. Well.

Then let me ask you again, what are the key points to pay attention to in stem cell differentiation? ”

Zhao Heng's answer was completely unexpected by Li Hongwei, so he decided to ask a more in-depth question, he wanted to find out where Zhao Heng was.

"The differentiation of stem cells should not only ensure that stem cells provide the body with a steady stream of functional progeny differentiated cells; It is also necessary to ensure that stem cells have sufficient reserves in their microenvironment. At the same time, it is necessary to prevent the depletion of stem cell reserves caused by excessive differentiation of stem cells; It is also necessary to avoid tumor-like structures caused by excessive proliferation of stem cells. ”

"Professor, am I right?" ”

Zhao Heng quickly retrieved the information in his mind and continued.

“。

You're right. So let me ask you again, how does factor 4 maintain the self-renewal of stem cells as part of the COP9 complex in stem cells? ”

"Also, how does the pro-differentiation factor BAM, which is abundantly expressed in differentiated progeny cells, compete for recruitment4 and thus transform other protein components to play a differentiation-promoting function?"

Li Hongwei saw that Zhao Heng had answered again, so he lost his calm a little and quickly asked the two questions he had just explored recently.

He didn't believe that Zhao Heng could still answer these two questions, that would be the hell!

"Hmm.

Zhao Heng pondered for a moment, these two questions were very difficult, even if he retrieved the knowledge and experience in his mind, it would take time, and he also had to organize the language and expression.

"It's okay, Xiao Zhao, you can't answer, it's normal."

Seeing that Zhao Heng stopped and looked like he was thinking hard, Li Hongwei breathed a sigh of relief, and instead comforted Zhao Heng and said.

To be honest, Zhao Heng was able to answer the previous two questions, and in Li Hongwei's opinion, this also has the potential to be his student and inherit the mantle.

You know, he doesn't take students easily.

"Professor, I've figured it out."

Just when Li Hongwei secretly breathed a sigh of relief, Zhao Heng opened his mouth and said, he had already organized the language.

"Huh? Did you come up with it? It's impossible, you name it! ”

Hearing Zhao Heng say this, Li Hongwei was a little incredulous, and asked repeatedly.

"4, is one of the self-renewal factors targeted by BAM, an evolutionarily conserved multifunctional complex containing 8 protein subunits, which act as follows:

Next, Zhao Heng spent nearly ten minutes expounding in detail the two most difficult questions raised by Li Hongwei.

When Li Hongwei first listened, he was a little unimpressed, but the more he listened, the more dignified his expression became, and Zhao Heng's level in cell fate regulation technology was completely beyond his expectations.

After listening to Zhao Heng's narration, Li Hongwei suppressed the excitement in his heart, and asked a question that he hadn't solved yet.

"As the only subunit of 4 and 8 that is not involved in stem cell differentiation, why do you think 4 has the opposite effect of other proteins?"

After asking this question, Li Hongwei stared at Zhao Heng tightly, he was really nervous at the moment.

“4？”

Zhao Heng heard Li Hongwei's question and fell into searching.

After a while, he shook his head at Li Hongwei and said, "I'm sorry, professor, I can't answer this question." ”

"Can't answer? Okay! No, not good. Xiao Zhao, you really gave me a big surprise! ”

Li Hongwei said with some indiscretion.

As soon as he heard Zhao Heng say that he couldn't answer this question, he suddenly felt relieved in his heart, if Zhao Heng could even answer this question, then Zhao Heng would be his teacher, not him being a teacher here.

"Xiao Zhao, next, you come to work with me. I believe that with your help, the time of one month can be shortened a lot. ”

Li Hongwei looked at Zhao Heng carefully, although he felt that Zhao Heng's level was incredible, and he felt frightened at first, but after the fright, it was full of surprises.

Zhao Heng is so young, he has such a level, why worry about scientific research!

"Well, trouble, Professor."

Zhao Heng nodded very humbly, without the slightest arrogance.

Using this kind of limelight to participate in the cultivation of stem cells, Zhao Heng is also to shorten the cultivation time, which is also a matter of no way.

What's more, Li Hongwei's actions are still very worthy of his admiration.

"Uh-huh, okay."

Seeing Zhao Heng's humble face, Li Hongwei was even more satisfied.
